Abstract

In a printed board unit (13), a semiconductor element (26) generates heat when the semiconductor element (26) operates. Heat from the semiconductor element (26) transfers to a package board (16) and a mother board (14). The thermal expansion coefficient of the package board (16) and that of the mother board (14) are different. Stress is generated in the package board (16). A reinforcing member (18) is stored inside a second prismatic space (33) on the package substrate (16). The reinforcing member (18) is bonded on the front surface of the package board (16) in a bonding region which spreads inward from the outer periphery. As a result, rigidity increase of the package board (18) is suppressed compared with a case where the reinforcing member (18) is bonded on the package board (16) outside the second prismatic space (33). Stress concentration at the corners of the package board (18) is eliminated. Breakage of the terminal bumps (17) on the bump row on the outermost circumference is eliminated.
